ticking ro knocking?????????? or torque converter
i was getting ready to pull my jeep to a wheeling trip and when i pulled into the driveway it sounded really rough... sounded like it was coming from the engine. but when i put it into gear, the noise when away for the most part...than when i actully drove forward or backward no noise execpt for idol in gear. it made the noise in park and nuetral. i just got this 99 f250 psd a week ago and they said when i got it the swaped a new 01 7.3 psd into it. could they have just not tightend down something or could it be like my mechanic said and a valve guide. or could it be something as simple as a loose wire.

might be a cracked fly wheel or bearing. my dads truck was doing the same thing last week. we had to replace the flywheel and rebuld the transmission

you mean flex plate? i don't think autos have flywheels....the jeep has a flexplate in place of what the manual flexplate
|

honestly buddy the way you discribe it, it doubt its a cracked flexplate because that should get worse in gear. Im thinking your right on about the torque converter. Ive heard this before and while not being there i cant tell you for certantly, my "hunch" says thats gonna be it....

oh i was just clearing the confusion of flywheel and flexplate, but yes marc, as you are always on the ball, i bet it is also

it was the flex plate cracked all the way around the crank flange.
sorry i didn't post results earlier... and the next thing you know my t conver. went out along with the tranny blowing a front seal. i swaped in a reman and new torq conv. and all problems went away for about a week untill the new flexplate was cracked, it is in the shop right now cuz i'm sick of pulling trannys... i guess for put in a new motor before i bought it. so i think something is tweeked. |
